Inquiry Regarding Fixed Parameter Addresses for Software Safeload (ADAU1452 vs. ADAU1466)
Dear SigmaStudio Support Team, We are currently implementing IPAT (Indirect Parameter Access Technique) to fix control addresses, with the goal of avoiding future modifications to MCU code. During thi

SafeLoad not working on ADAU1467
Hello, I'm working with the ADAU1467 and trying to write filter coefficients via SPI using the SafeLoad mechanism. When I write the filter coefficients directly to memory, everything works perfectly.

SafeLoad-sequence for 'Boost'-filter block.
We have a FDSP schematic designed w. "LarkStudio". A 'Boost' IIR 8-stage filter-block (peaking-filters) is used for audio equalizer functionality. To enable run-time setting of audio-band properties,

How to write volume value from spi-connected Arduino to safeload?
Hi. My problem is that I shut down the power using push volume on adau1466 When turned on, the volume is initialized (interface read, write does not work) So, by connecting Arduino Nano with SPI, I wa

ADAU1452 SigmaStudio Update Parameters with Safeload
Hi all, Hopefully this is a simple question. I want to update the frequency of the built-in triangle wave generator using a potentiometer connected to AUX_ADC_0. I'm able to update parameters such as

ADAU1452 PEQ safeload
I'm developing a board composed of MCU and ADAU1452. SigmaStudio v3.13 is used to create block diagrams. MCU can make ADAU1452 work by I2C,also can Control the volume. SO I think I2C operation has no

Safeload using I2C on ADAU1787
Hi ADI I am busy developing code for an ADAU1787 connected to a MCU via I2C. I am able to connect, load code and communicate with the SigmaDSP. Using direct memory writes I am able to change the gain

Filter coefficents order in Safeload operation
I'm working on ADAU1467 in combination with an STM32F4 microcontroller. In red below the question. In order to implement a Safeload operation to update filter coefficents I saw that from my "*_PARAM.h

Alsa control generation for filters (feature request for sigmastudio)
Hi, I am using the adau1761 in a linux environment where I have built my project in sigmastudio and thereafter used the linux fw-tool to generate the binary from the project xml-file. When I have load

I2C Safeload problem on ADAU1452
Hello, we try to write to the safeload mechanism from a PIC24FJ128GA108 uC over I2C to an ADAU1452 DSP. In the compiler_output.log the SafeLoad_Module addresses have been verified. In the first step w

safeload parametric equaliser settings
Hi, I am playing around with an Arduino controlling a 1701 controlling 4 channels, each channel has delay, gain and a parametric equaliser.. I have organised the math required and writing the biquads

How is SafeLoadModule activated for ADAU1466?
I have a processing scheme for the ADAU1466. I export the files in C with the Export System Files button and in the parameters file I have the following: /* Module SafeLoadModule - SafeLoadModule*/ #d

safe load cause noise in SS3.9?
Hi all, Tools: the latest SigmaStudio v3.9 When we access the safe load register on the ADAU1702 it happens frequently that the DSP afterwards makes a lot of noises. When we use the same software in a

Real Time Control TUTORIAL: SAFELOAD, Fixing and Breaking variables
Hi There, how are you all? I've seen around here many people having trouble to control Sigma DSPs in real time. So I decided to write a little "walkthrough" guide. Let's get started: Now that you SOME

Software safeload examples
In order to use software safeload to write data to parameter RAM, at least three writes must be performed. First, the data is loaded into the safeload data registers (addresses 0x0001 through 0x0005),
